Southwest Research Institute (SwRI) contracted with a large U.S. engine and equipment manufacturer to redesign the turbocharging system of a large mining truck engine. The redesign was intended to solve problems of turbocharger rotor failure and air handling
system seal failure due to the high temperatures of the compressor outlet air. SwRI work scope included incorporating the new turbocharging equipment, redesigning all the air ducting including several major castings, and redesigning all of the auxiliary equipment including oil
lines, coolant lines, access steps, and various brackets and miscellaneous parts.
Three-dimensional design work was done using Pro/ENGINEER as a solid modeler. Several concepts were developed and analyzed for their improvement of the design and reduction in parts count. A significant reduction in parts count and combination of functions within single
castings realized increased reliability. Incorporating steel bellows to accommodate relative motion caused by thermal growth solved the seal problem.
SwRI participated in the prototyping process by interfacing with casting and machining vendors, fabricating some of the prototype hardware, traveling to the client's facilities to assist in buildup and assembly checks, resolving field problems, and finally preparing all
of the manufacturing drawings for the new components and assemblies.
The new turbocharging system is now in production and has successfully addressed the problems.
